Biodegradation of Nitroaromatic Compounds and Explosives gives you a synthesis of ongoing research and an appreciation of the remarkable range of biochemical strategies available for the transformation of nitroaromatic compounds.

It provides a realistic assessment of the current and potential field applications of the various strategies. Buy Biodegradation of Nitroaromatic Compounds and Explosives (): NHBS - Edited By: J Spain, Lewis Publishers About Help Blog Jobs Established NHBS GmbH Covid £ GBP.

The combination of sonolysis and ozonolysis as an advanced oxidation process was investigated to gain insight into factors affecting enhancement of the combined system.

Sonolysis, ozonolysis, and a combination of the two were used to facilitate the degradation of three known organic contaminants, nitrobenzene (NB), 4-nitrophenol (4-NP), and 4-chlorophenol (4-CP), in by: The best-known nitroaromatic compound is the explosive TNT (2,4,6-trinitrotoluene).

The optimal remediation strategy for nitroaromatic compounds depends on many site-specific factors. Abstract Published in the series Analyses of Hazardous Substances in Biological Materials, Vol.

3 () The article contains sections titled:Cited by: 1. p-Nitrotoluene (PNT) is a nitroaromatic compound that is hazardous to humans and is a suspected hormone degradation of PNT in aqueous solution by ozonation (O 3) combined with sonolysis (US) was investigated in laboratory-scale experiments in which pH, initial concentration of PNT, O 3 dose and temperature were varied.

The degradation of PNT followed pseudo-first-order. In nature, nitroaromatic compounds are mostly found in natural products from different plants, fungi, and bacteria [5, 6]. The best known example of this is chloramphenicol, which is produced by Streptomyces venezuelae [7–9].

The role of some nitroaromatic compounds in cellular signaling has also been established. This book is the result of their efforts. The emphasis of the reviews is on basic research in biodegradation and biotransfor­ mation.

Therefore, the reactions of nitroaromatic compounds in plants, animals, bacteria, fungi, soil, and even nonbiological systems are considered.

Single ozonation of two nitroaromatic hydrocarbons (nitrobenzene and 2,6-dinitrotoluene) under different experimental conditions (ozone feed rate, pH, temperature, hydroxyl radical scavengers) has been studied.

The absence of hydroxyl radical scavengers, pHs 7−9, and temperatures below 30 °C are optimum conditions for nitroaromatic removal. Due to the importance of hydroxyl. Other polynitro compounds that are useful as explosives include PETN (Section C), cyclonite (Section C), picric acid, and tetryl: An important characteristic of aromatic polynitro compounds is their ability to form "charge-transfer" complexes with aromatic hydrocarbons, especially those that are substituted with alkyl groups.

Filled with practical applications and research, Biodegradation of Nitroaromatic Compounds and Explosives presents an international perspective on environmental contamination from explosives.

It covers biodegradation strategies for DNT and a wide variety of other nitroaromatic compounds of environmental significance and makes the information access. mineralize a variety of nitroaromatic compounds. For example, Phanerochaete chtysosporium mineralizes 2,4-dinitrotoluene and 2,4,6-trinitrotoluene and shows promise as the basis for bioremediation strategies.

The anaerobic bacteria and the fungi mentioned above mostly transform nitroaromatic compounds via fortuitous reactions. This book provides useful information about bioremediation, phytoremediation, and mycoremediation of wastewater and some aspects of the chemical wastewater treatment processes, including ion exchange, neutralization, adsorption, and disinfection.

Additionally, this book elucidates and illustrates the wastewater treatment plants in terms of plant sizing, plant layout, plant design, and plant. Toxicity of Nitroaromatic Compounds (Chemical Industry Institute of Toxicology Series) 1st Edition by Douglas E.

The UV–H 2 O 2 process, a standard advanced oxidation process (AOP) for water treatment, has been applied to the degradation of a series of nitroaromatic compounds (nitrobenzene, 1-chloro-2,4-dinitrobenzene, 2,4-dinitrophenol, 3-nitrophenol, 4-nitrophenol and 4-chloro-3,5-dinitrobenzoic acid) using polychromatic radiation sources.

SUMMARY Nitroaromatic compounds are relatively rare in nature and have been introduced into the environment mainly by human activities. This important class of industrial chemicals is widely used in the synthesis of many diverse products, including dyes, polymers, pesticides, and explosives.

Unfortunately, their extensive use has led to environmental contamination of soil and groundwater. There is an urgent need for new, safer, and effective treatments for the diseases caused by the protozoan parasites Trypanosoma brucei, Trypanosoma cruzi, and Leishmania spp.

In the search for more effective drugs to treat these ‘neglected diseases’ researchers have chosen to reassess the therapeutic value of nitroaromatic compounds. Nitroaromatic explosives, such as 2,4,6-trinitrotoluene, are representative aromatic compounds, which are generally highly toxic.

For their toxic mechanisms, little is known about their interaction with cell membranes, although this is essential for their absorption. Sonolysis of Nitroaromatic Compounds, 1,3-dinitrobenzene and Nitrobenzene.

Since one of the effects of sonolysis on water is the breakdown of water to produce hydroxyl radicals, this work.The initial reduction steps of nitroaromatic compounds on the surface of metallic iron have been studied theoretically using nitrobenzene (NB) as a representative of nitroaromatic compounds.

The quantum chemical cluster approximation within the semiempirical Neglect of Diatomic Differential Overlap for Metal Compounds method was applied to model the Fe() crystallographic surface, taken as a.
